Windows Management Instrumentation (WMI)
Windows Management Instrumentation (WMI) offers a way to gather a system information from a computer.
WMI is Microsoft's implementation of the Web-Based Enterprise Management (WBEM) and Common Information Model (CIM) standards from the Distributed Management Task Force (DMTF). WMI allows Windows PowerShell to manage Microsoft Windows personal computers and servers, both locally and remotely. WMI consists of classes that are made up of properties and methods that we can manipulate with PowerShell scripting
To see WMI on our system do the following:
- Open 'Computer Management' from Administrative Tools.
- Expand 'Services and Applications.'
- Right-click 'WMI Control' and choose Properties.
- Click on the Advanced Tab. Notice: Default namespace for scripting by default set to root/cimv2.
A typical Windows computer will contain tens of thousands of pieces of management information, and WMI seeks to organize that into something that's approachable and more or less sensible.
At the top level, WMI is organized into namespaces. Think of a namespace as a sort of folder that ties to a specific product or technology.
For example, the root\CIMv2 namespace contains all of the Windows operating system and computer hardware information; the root\MicrosoftDNS namespace includes all of the information about DNS Server.
On client computers, root\SecurityCenter contains information about firewall, antivirus, and antispyware utilities
WMI CIM Studio
WMI CIM Studio which provides a GUI into the WMI hierarchy. We'll see how WMI CIM Studio and PowerShell are used to find Classes, Properties, and Methods. The WMI Administrative Tools are available from WMI Administrative Tools. After installed the WMI Tools, we launch WMI CIM Studio from Start => Programs => WMI Tools:
- Allow blocked content - if your browser is locked down.
- We will be prompted to connect to namespace: make sure 'root/cimv2' is selected - click OK.
- Click OK to use current user log on. Local Admin Rights are required.
- Click on the binocular icon to search for a class.
- In the search box type processor and click GO! for results.
- For now we are interested in the Win32 classes.
- Choose Win32_Processor and click OK.
The left pane displays the classes available and the right pane shows which properties(tab) and methods(tab) are available for the selected class. In our case the selected class is Win32_Processor.
